(a) Spermatogenesis or the formation of sperms in human beings occurs by the process of meiosis. It results in the formation of four equal-sized daughter cells.
(b) Oogenesis or the formation of ovum in human beings occurs by the process of meiosis. It results in the formation of four daughter cells which are unequal in size i.e. are big mature ovum and 3 smell polar bodies.
Define a taxon. Give some examples of taxa at different hierarchical levels.
What are the steps involved in formation of a root nodule?
Define sliding filament theory of muscle contraction.
There are only two polar body formed during a oogenesis process.and they degenerate due to insufficient of cytoplasm.
